Early-term results of coronary artery bypass grafting in renal transplant patients

Abstract

Background: Cardiovascular disease is the most common cause of mortality and morbidity in kidney transplant patients. Many case reports and case series about coronary artery bypass grafting operation after renal transplantation have been presented. In this article, we aim to evaluate the patients undergoing coronary artery bypass surgery after renal transplantation. Methods: Among the 4330 patients who underwent CABG between January 2012 and December 2021, there were 11 patients who had a previous renal transplant. Seven patients (64.6%) were male and four (35.4%) were female. The median age of the included patients was 52 (42–66). Results: While ten patients (90.9%) received CABG electively, one patient (9.1%) underwent emergency surgery. Intra-aortic balloon pump was used preoperatively to the urgent patient. On-pump CABG was applied in six patients, off-pump CABG was applied in four patients and beating CABG procedure was applied in one patient who was urgent. Atrial fibrillation developed in three patients (27.3%) in the postoperative period. The length of stay in the intensive care unit was 3±1.6 days, and the length of hospitalization was 8±3 days. Conclusion: It showed that having a renal transplant does not carry an extra risk in terms of mortality and morbidity when performing CABG. Renal transplant patients should receive immunosuppressive therapy and should be monitored closely in terms of renal function. In these patients, the multidisciplinary approach becomes even more important.
